Described are a vehicle optical communications system and network to exchange high bandwidth optical data between vehicles or between a vehicle and a stationary host. The vehicle optical communications system includes a communications module and a sensor having pixels for detecting an image in a field of view. Each pixel can generate a pixel data signal responsive to an incident optical data signal that includes vehicle data transmitted from a remote optical transmitter. The communications module provides remote data in response to the pixel data signals. The vehicular communications system optionally includes an optical transmitter to enable bi-directional communication. Data can be transmitted through a multi-node network of vehicular communication systems deployed in vehicles or on stationary hosts located between or around the data transmitter and intended data receiver. Simultaneous data from multiple optical transmitters within the sensor field of view are processed concurrently and maintained as separate communication channels.

Vehicular optical communications system

Described are a method and optical communications processor for receiving communications data in an image formed on a plurality of pixels. The method includes receiving active pixel information identifying which of the pixels are receiving communications data and retrieving communications data from each of the pixels identified by the active pixel information. A list of active data communication channels is generated in response to the active pixel information. The active pixel information can be in the form of active pixel flag bits. Optionally, the method also includes receiving video data from the pixels.

Optical communications imager

Described are a method and a photodetector system for determining a wavelength of light. A current generated in a photodetector in response to incident light is determined. The incident light is terminated and a decay current generated by the photodetector is determined. The wavelength of the light is determined according to the current, the decay current and a predetermined correspondence between the current and decay current as a function of wavelength and time. In one embodiment, the decay current is compared to reference decay currents to determine a matched reference decay current and the wavelength of the light is determined according to a wavelength associated with the matched reference decay current.

Method for determining wavelengths of light incident on a photodetector

An apparatus and method for semi-automated generation and application of language conformity tests is disclosed. Generation is based on interpretative or compiled processing of a generator-oriented, formal language specification embodying lexical, syntactic and semantics aspects of a language standard as well as specific test strategies. Such test strategies control the order and extent of the test sequence generated and applied. Both test case generation and application of test cases may occur in parallel.
